## Abstract Medium harvested from cultures of mouse Lβcells contains βconditioning factor activityβ (CFA) that may be detected by its ability to stimulate colony formation by mouse marrow cells in culture. The active material has been characterized and appears to be a glycoprotein with properties s
## Abstract Molecules of low molecular weight, able to stimulate colony formation by human granulopoietic cells, were prepared from media conditioned by normal and leukemic human peripheral blood leukocytes. When molecules from these sources were studied, heterogeneity was observed in their ability
